EXHAUST-HEAD.

SPECIFICATION forming part of Letters Patent No. 487,723, dated December13, 1892.

Application tiled April 29. 1892. Serial No. 431,097. (No model.)

To all whom it may concern.

Be it known that I, JULEs JOHN JOSEPH DE RYCKE, a resident of Brooklyn,Kings county, and State of New York, have invented an Improved ExhaustHead and Condenser, of which the following is a specification, referencebeing had to the accompanying draw Y ings, forming part hereof, inWhich- Figure l is a vertical central section of my improved exhausthead and condenser, the line l l, Fig. 3, indicating the plane ofsection. Fig. 2 is a side elevation of the interior portion of saidexhaust head and condenser, showing the exterior portion in section.Fig. 3 is a horizontal section on the line 3 3, Fig. '1. Fig. 4 is adetail vertical section on an eularged scale of the Lipper annulartrough.

The object of this invention is to produce mechanism to be placed onroofs of buildings and the like for condensingtothefullestpossibleextent any oil carried away by exhauststeam from engines and as much ofthe water of said steam as practicable, so that the steam will beliberated from impurities and will be prevented from soiling garmentsand other things on the roofs of such buildings.

The invention consists of the combinations and arrangements of partsthat are hereinafter more fully specified and described.

In the drawings the letter A represents the outer casing of my improvedexhaust head and condenser. This outer casing has, by preference, acylindrical central portion and contracted ends, as shown, the lower endbeing adapted to be placed upon the root` of a house and being open toreceive the exhauststeam from the exhaust-pipe of an engine, Whereas theupper end of said casing is also open to allow the escape of the steam.That part of the outer casing which is cylindrical is double walled, theinner shell or Wall c. being shaped in resemblance of a ratchet-wheel,so as to produce upright slits or openings d. The lower end of thisratchet-like interior shell a, which, as before stated, is by preferencearranged only within the cylindrical portion of the casing A, lout whichmay, if desired, be carried beyond said cylindrical portion, embracesand is a short distance away from a lower inner wall b, which at itslower end connects with the outer Wall of the casing, as shown. Thesmall space between the lower end of the shell a and the upperend of theshell b is shown at b in the drawings. The space between the casing Aand the ratchet-like inner shell a is marked d2 in the drawings. Thespace between the lowermost inner wall b and the outer jacket or casingA is represented by the letter b2 in the drawings, and is the receptaclefor the products of condensation, from which receptacle said products ofcondensation can escape by a pipe K. Within the center ot'- the casingA-and its double wall, dto., is arranged an interior upright casing B,whose central portion is also, by preference, cylindrical, and whoseends are tapering, as represented; but both ends are open for theadmission and discharge of air, as hereinafter more fully described. Thelower open end of thisiuner structure B communicates with an air-inletpipe F, as clearly shown in Fig. l, so that through this pipe F airenters the lower end of the chamber B, and it escapes from the upper endof said chamber B by a pipe m, extending upwardly therefrom, as shown,into a hood-like structure H, which is fixed by brackets g to theinterior of the upper portion of the casingA. The lower part of thecentral chamber B enters into a cup I, which communicates' by a pipe 1'.with the chaber b2, so that any products of condensation that run downon the outer side of the structure B will be received in the cup I andcarried off by the pipe Within the central structure B is contained aninterior shell D, having tapering lower portion and, by preference,cylindrical main body. This vessel D is by brackets d held at a shortdistance from the inner wall of B, so as lto form a narrow air-spacebetween the two parts B and D.

Between the central structure B and the inner shell a of the outercasing are spirallyarranged flanges or blades E, as shown. These bladesmay be affixed to the-central structure B or to the outer structure A,or to both, as may be desired. The annular trough L is placed over thetop of the inner shell a to receive drippings from the inner side of theupper portion ot the casing A, drip-holes in the bottom of said trough Lleading to the space a2, and thence to the receiving-space b2.

Having now described the construction of my apparatus, I will briedystate how it opcrates. The structure being placed upon a roof in uprightor other position communicates, as before described, at its lower endwith the exhaust-steam pipe and receives the full head of steam in saidopen lower end. This steam, rushing up within the space traversed by theblades E E and between the structures B and A, receives a whirlingmotion by means of said blades, which causes the centrifugal forceimparted to it to deposit on the inner wall of the ratchet-like shell aproducts of condensation. These products of condensation are hurledthrough the slots a into the space a2, and then iiow down along theinner wall of the casing A, and possibly also along the outer side ofthe shell a into the final receiving-chamber or drip-chamber b2, whencethey escape through the pipe K. Meanwhile air travels up through thepipe F and through the spacef between the vessels B and D and helps tochill the wall of B, so as thereby to assist in proper and rapidcondensation, the interior vessel D serving to make the air-film narrow,and to therefore enhance the cooling action. The flow of air is furtherhastened by the hood H, which being open to the escaping steam andplaced overthe air-outlet m causes the steam to exert suction upon theair be neath and to help draw out the air from the vessel B. Anyproducts of condensation that lodge against the inner wall of the casingA, above that part where the same is lined with the shell a, fiow downinto the trough L, and thence drip into the chamber a2 and b2. Anyproducts ot' condensation that collect along the outer wall of B iiowdown along said outer wall into the cup I, and thence by the pipe z'into the drip-chamber b2.

Having now described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the outer casing A, open at both ends, with theinner slotted shell a, spiral blades E, and interior cone B,substantiallyas and for the purpose herein shown and described.

2. The combination of the outer casing A, inner slotted shell a', andlower inner shell b with the spiral blades E and interior cone B,

all arranged so that drip-openings b are formed between the shells a andb and so that spaces a2 and b2 are formed between the casing A and innershell a and between the casing A and inner shell b, respectively,substantially as herein shown and described.

3. The combination of the casing A and inner perforated shell a with thespiral blades E, central cone B, upper perforated trough L, and lowerdrip-chamber b2, having outlet-pipe K, substantially as described, andfor the purpose specified.

4. The combination of the outer casing A with the independent inner coneB, open at both ends, whereby the air can be taken in at the bottom anddischarged directly into the atmosphere at the top, and with theair-inlet pipe F, connected to said inner cone, all substantially as andfor the purpose herein shown and described.

5. The combination of the outer case A, inner cone B, open at both ends,air-inlet pipe F, and central vessel D, placed within theinner cone B,whereby the air is forced against the sides of said inner cones B,substantially as and for the purpose herein shown and described.

6. The combination of the outer case A with the central cone B, open atboth ends, air-inlet pipe F, air-outlet pipe m, and upper hood H, allarranged substantially as and for the purpose herein shown anddescribed.

7. The combination of the outer casing A, outer chamber b2, spiralblades E, central cone B, air-inlet pipe F, cup I, and pipe t', allarranged substantially as and for the purpose herein shown anddescribed.

8. The combination of the outer casing A with the perforated inner shella, lower shell b, forming drip-chamber b2, upper perforated trough L,spiral blades E, central cone B, open at both ends, air-inlet pipe F,air-outlet pipe m, hood H,cnp I, and pipe e', all arranged substantiallyas and for the purpose herein shown and described.
